You can buy a Lee Universal decapper.
If brass was really dirty, I'd run it through the cleaner first for a cycle regardless the directions before rubbing the crap through dies: Afterward I'd clean the cases as usual. I have also vigorously shaken brass in a sealed bucket of water to remove the abrasive range grit. In a case like 9mm, I have also used a 45acp die on small scale to pop out primers but I still don't like having dirt anywhere near the bench and equipment.
Wasn't anywhere near "bomb defusing level of stress" I was expecting either. Felt a little silly sitting at my bench rigged up like I was at the range
You too, eh? LOL I was all done up just in case
eheheh, yep. I guess the warning siren I sounded caught the attention of my g/f. She came downstairs, somehow got around the yellow "WARNING" tape and sand bags I had setup, looked at me and said "um...watcha doin?"
I yelled "CLEAR" and raised the ram. Primer simply fell out. Huh....that was rather anti climactic.
Wise to be careful. At a BR match, a fellow pushing out live primers had one go off. Made a nice primer size hole in his jeans and thigh. He had to go to the doctor's to dig the thing out when it started festering.
